title: Hypomelanosis in tuberculosis--unrelated to anaemia.
abstract: Previous work has shown that hypomelanosis is a useful sign to aid suspicion of tuberculosis in patients with dark skins. This study has confirmed that it is unrelated to haemoglobin levels. A simple colour card 'melanometer' for clinical use is described. As hypomelanosis has not been noted in HIV infection in African, and as tuberculosis is an important differential in case-definition where diagnostic facilities are limited, it is suggested that more clinical research on hypomelanosis in relation to disease is urgent.
